SSID Identification for Automatic IPv6 Wireless Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to automatically set wireless network parameters when using Internet Protocol Version 6 (IPv6), as they are designed for IPv4 and cannot include additional information in the Service Set Identifier (SSID), leading to difficulties in establishing connections and increased setup time.
Innovation Solution
A wireless communication system where the first terminal generates an SSID without an IP address, allowing for automatic or simple operation of wireless network parameter setting, enabling connections based on shared wireless setting information, regardless of whether IPv4 or IPv6 is used, and reducing the amount of information exchanged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an IP address is included in the SSID to enable automatic wireless network parameter setting, then wireless connection establishment is enabled, but the SSID cannot accommodate additional information when using IPv6 due to length constraints
Solution Approach 1:
The patent segments the information transmission process by separating the SSID (used only for identification) from the IP address (transmitted separately through other beacon fields). This allows the SSID to remain within length constraints while still enabling automatic connection setup through alternative information channels.
Solution Approach 2:
The patent moves the IP address information from the one-dimensional SSID field to other available fields in the beacon signal, effectively utilizing additional dimensions of the data structure to accommodate IPv6's larger address requirements without compromising SSID functionality.
2Ease of operation
If wireless network parameters are set automatically through the SSID, then user operation is simplified, but the amount of information exchanged increases connection establishment time
Solution Approach 1:
The patent extracts the IP address from the SSID and transmits it through separate, more efficient beacon fields. This separation allows the SSID to quickly identify the target network while the IP address is transmitted through optimized channels, reducing overall connection establishment time.
3Extent of automation
If the SSID includes comprehensive wireless setting information, then automatic connection is enabled, but packet loss increases connection failure rate
Solution Approach 1:
The patent segments critical connection information into multiple transmission channels within the beacon signal. By distributing information across different fields rather than concentrating it all in the SSID, the system reduces vulnerability to packet loss and improves connection reliability.

AI summary
A wireless communication system includes a first wireless terminal including a first network control unit that sets first wireless setting information as current wireless setting information of the first wireless terminal, a generating unit that generates an SSID including identification information of the first wireless terminal, and a first wireless communication unit that transmits a beacon including the SSID; and a second wireless terminal including a second wireless communication unit that receives the beacon, an extracting unit that extracts the SSID from the beacon and extracts the identification information from the SSID, and a second network control unit that sets second wireless setting information, stored in the second wireless terminal and corresponding to the first wireless setting information, as current wireless setting information of the second wireless terminal and establishes a wireless connection with the first wireless terminal based on the identification information and the second wireless setting information.
